CAR-=AXLE Box.

SPECIFICATION forming part of Letters Patent No. 299,320, dated May 27, 1884.

Application filed February 23, 1884. (No model.)

Be it known that 1, WILLIAM S. G. BAKER, of Baltimore, Maryland, haveinvented certain new and useful Improvements in Car-Axle Boxes, of which the following is a specification.

My invention relates to the lubricating devices; and involves certain improvements n the structure of the box proper.

Referring to the accompanying drawings, Figure 1 is a side view, partly in section, of one form ofmy improved box; Fig. 2, a transverse section of the same on the line 2 2 of Fig. 1; Fig. 3, a longitudinal horizontal section on the line 8 3 of Fig. 1; Fig. 4, a side view, partly in section, on the lines 44 and m 00 of Fig. 5, of a modification of my improvements; and Fig. 5, a transverse section of the same on the line 5 5 of Fig. 4.

In Figs. 1, 2, and 3 the box A is shown as formed with a longitudinal partition, B, which extends from front to rear of the box just below the axle. Ihave shown the partition as formed integrally with the box; but it may be made separate and removable, and held in place in suitable sockets or by bolts. Each side of the partition is formed with longitudinalslots or recesses a. It will be observed, however, that the partition extends entirely across the box at both the front and rear ends, and fits its interior contour snugly. This feature is of great importance, especially as to the rear of the box, as will be more fully explained further on. Sockets I) (preferably two in number) are formed in the partition B, and receive dowels c, that are secured; to a metallic plate or pad-holder, d. The plate (2 extends longitudinally through the box, and preferably has a concave upper face corresponding to the curvature of the journal 0, and its lateral edges may be bent over, as shown in Fig. 2. Springs 6 are interposed between the plate and the partition, and, as the dowels are free to move in their sockets, the plate or padholder is free to automatically rise or fall, as occasion may require. A pad, D, of felt or other suitable material, is secured to the plate or holder (2 and completely covers its upper face. The ends of the pad extend down through the recesses a into the oil-cellar E be- 7 low. The pad should be arranged to completely fill the recesses from end to end, and to bear against the sides of the box, so as to prevent the oil from finding its way out of the cellar except by way of the pads,through which it is drawn by absorption or capillary attraction to feed oil to the journal. It should be especially noted that the oil is preventedfrom slopping out at the back of the box through the opening for the axle. As before stated, the partition extends entirely across the box at this end, and as the felt completely fills the recess, the oil cannot possibly overflow or spill out. Any oil that may drop from the journal will be caught and held in the concave face of the pad.

In Figs. 4 and 5 I have shown a removable oil receptacle or drawer, F, preferably made of sheet metal, and shaped to fit snugly the interior of the box below the journal. The re ceptacle or drawer F is formed with a partition, B, similar to that shown in Fig. 3,and the pad D, pad-holder d, and its yielding supports are also similarly arranged. In this instance the lid of the box is'hinged at the bottom of the box, so that when swung open the drawer may be readily removed. I do not, however, claim a removable oil-receptacle or a lid hinged at the bottom of the box, but merely show such a construction to illustrate the application of my improvements thereto.

I claim as my invention- 1. The combination, substantially as set forth, of the box, the partition,which extends horizontally entirely across the box at its rear end and is formed with side openings or recesses, and the lubricatingpachwhich extends up through one of said openings, under the journal, and down through the other opening, so as to present an extended lubricatingsurface to the journal.

'2. The combination, substantially as set forth, of the box, the partition,which extends through the box from end to end and horizontally entirely across the box at both ends, and is formed with side openings or recesses, and the lubricating-pad, which extends through the openings, so as to completely fill the same from end to end, and which presents an extended lubricating-surface to the journal.

3. The combination, substantially as set forth, of the box, the lubricant-chamber, the

partition located over the lubricant-chamber, sockets formed therein,the pad-holder, and the and the concave pad-holder mounted on the dowels connected thereto that work in the partition. sockets in the partition.
